Hi there! I understand you're having trouble editing anything in your TeamReach calendar. To help you best, could you share a bit more? For example, are you unable to edit all calendar events or just certain ones? Are you logged in as an admin, leader, or member? Also, have you recently changed devices or accounts?

In the meantime, here are some common steps to try:

1. Check Your Access Level: Usually, only admins or leaders have editing permission on the TeamReach calendar. If your role changed or your leader access was lost, that could block editing.

2. Confirm You're Logged In Properly: Sometimes switching devices or rejoining groups can affect your permissions.

3. Update the App: Make sure your TeamReach app is the latest version, as older versions might have bugs affecting calendar editing.

4. Check Your Device Time & Time Zone Settings: Incorrect time or time zone settings on your Windows 10 device could cause calendar sync and editing issues.

If you verify all these and still can't edit, let me know about your role and any recent account changes. We can then explore deeper possibilities like refreshing permissions or checking for app bugs.

Does this sound like what you're experiencing? If so, which steps have you tried so far?
